Jane Street sharply reduced its exposure to Bitcoin ETFs in the first quarter of 2026, reducing reported positions in BlackRock’s IBIT and Fidelity’s FBTC, while increasing positions in Ether ETFs and several crypto-linked stocks. The move has revived speculation that one of the market’s largest trading firms may have been a major factor in Bitcoin’s recent price dynamics – and that a lighter reported position could remove a key overhang for BTC.
According to the latest 13F filings, Jane Street cut its IBIT position by about 71% and its FBTC position by about 60% in the first quarter. Parker White, the Chief Operating Officer (COO) and Chief Investment Officer (CIO) of DeFi Development Corp (DFDV), renewed his thesis from February, arguing via
“It’s now clear that Jane Street cut their IBIT and FBTC holdings by about 70% in the first quarter based on 13F filings,” Parker wrote on
It is now clear that Jane Street has reduced their IBIT and FBTC holdings by approximately 70% in the first quarter based on 13F filings. Did they just sell outright or, more likely, did they make a HUGE profit on their short derivatives (which they don’t have to report)?

The filing does not demonstrate Jane Street’s derivatives exposure or whether the firm was bearish, hedged or engaged in ETF arbitrage and market-making activities. That limitation is central to the debate. A 13F includes certain long positions at quarter end, but does not provide a complete picture of options, swaps, futures or short positions that could materially change the economic interpretation of the reported reductions.
Still, the downgrade has become a point of concern due to previous claims that Bitcoin price discovery may be distorted by the mechanics of spot ETF trading. Bitwise advisor Jeff Park wrote that Jane Street had “reduced its Bitcoin ETF exposure in the first quarter of 2026,” cutting IBIT by about 71% and FBTC by about 60%, before adding: “Price discovery is back on the menu.”
Park’s broader argument is not that one company has explicitly suppressed the price of Bitcoin, but that the ETF structure creates a complex market-making environment in which authorized participants can use creation and redemption mechanisms, derivatives and futures hedges in ways that could weaken the link between ETF demand and spotting Bitcoin purchases. In an earlier post, he called the issue structural rather than conspiratorial.

“The short answer is that no AP explicitly suppresses the Bitcoin price,” Park wrote. “What the AP structure can suppress is the integrity of the price-setting mechanism itself. They are not the same, but the latter is arguably more consequential than the former.”

That distinction is important for the bullish interpretation. If Jane Street’s reported Bitcoin ETF exposure has already been substantially reduced, some traders may read the filing as evidence that a major source of ETF-related pressure has been partially alleviated. Parker went further, suggesting that Jane Street “probably doesn’t want to stay short BTC forever” and that observers should “look to see if they can re-accumulate in the second quarter.”
The statement is speculative, but not without a clear market logic. If a major trading firm had been involved in strategies that created sustained pressure on ETFs or derivatives, a reduction in reported Bitcoin ETF positions, coupled with an eventual unwinding of related positions, could return the market balance to cleaner spot-led price discovery. That’s the bullish setup implied by the messages: not just that Jane Street has been sold, but that the transaction may have already occurred.
At the same time, Jane Street did not broadly abandon cryptocurrency exposure. The firm increased its holdings in BlackRock and Fidelity Ether ETFs and expanded positions in Riot Platforms, Coinbase and Galaxy Digital, while trimming Strategy and several Bitcoin mining names.
At the time of writing, BTC was trading at $79,783.
